H EATING APPARATUS.-

SPECIFICATION forming part of Letters Patent No. 306,707, dated October 14, 1884-.

Application filed October 11, 1882. (No model.)

T at whom, it may concern:

Be it-known that we, OonYnoN \VHEAT and ALFRED OATOHPOLE, citizens of the United States, residing at Geneva, in the county of Ontario and State of New York, have invented certain new and useful Improvements in Heating Apparatus, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain improvements in heating apparatus for greenhouses and other structures; and it consists in a particular combination or system of steam and water pipes, whereby the water is heated and caused to circulate, as more fully hereinafter specified. I

In the drawings, Figure 1 is a plan view of the system of steam-pipes leading from the boiler and branching into waterpipes and returning therefrom and the reheatingdrum. Fig. 2 is a vertical section of one form of a reheating-drum and apparatus. Fig. 3 represents an elevation of a furnace, showing the connections of the steam and other pipes and a reheater connected to the main stcampipe and to the boiler. Fig. 4: is a plan view of a system of three pipes for water, the central pipe inclosing the steam-pipe. Fig. 5 is .a sectional view of a modification of the expansion-tank forming a portion of my improved system.

In the drawings, the letter A indicates a steam-pipe leading from a boiler. At A the said pipe, as shown in Fig. 1, branches to the right and left. From suitable couplings smaller pipes a a are led into the water-pipes 13. The said pipes a a are carried backward, after being extended a sufficient distance into the pipes B, and pass out of the watenpipes, and are conducted downwardly by branch pipes Z) Z) 1) into the top of a reheatingdrum, B, as indicated in Figs. 2 and 3. In Fig. 3 the reheater is connected to the steampipe A by a short tube, a, which supplies said reheatcr with steam. From the bottom of the reheater B a drip-pipe, 0, extends, connecting with a branch pipe, 0, from the bottom of the boiler. Another pipe, 0, eX- tends from the branch pipe 0, and a vertical pipe, 0, connects with it and with the re-v hcater B just above the bottom, which pipes the chamber as it passes down.

plied with steam from a reheater connected 95 c c conduct down any condensed steam which may be formed in the reheater. Suitable valves are fitted to these steam-pipes to control the course of the steam and water. The steam -pi'pe passes through one end of the waterpipe, and makes a return, and passes out again at the same end. The condensed steam is admitted by the pipe 12 and passes down to the collectionrhamber D at the bottom, being heated by the steanrpipe within At the bottom of the collection-ehamber a pipe, 0 is connected for the purpose of removing any sediment which may accumulate. The pipe (1 d, from the top of the reheater B, is connected with the boiler, for the purpose of reheating the return-pipe a.

The letter B indicates an expansion-tank, which may be placed at any point of the water-pipes. The said tank is open at the top, and has within it a cylinder, F, closed at the top and openat the bottom, which acts as a float .and prevents .the evaporation of water and the escape of steam and its condensation on surrounding objects on the discharge-of water from said expansion-chamber.

. The operation of our invention being set forth in connection with the above description, further reference to it is deemed unnecessary.

. WVe are aware that the steam-pipe has passed entirely through the hotwater pipe from end to end; but this system is objectionable, as it necessitates an extra, length of return-pipe, which being exposed, a largc'amount of heat is lost by radiation.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

The combination, with the system of inclosed hot-watercirculating pipes, of the steam-heating pipes entering and returning through one of said hot-water pipes, and sup directly to a steam-generator.

In testimony whereof we atfix our signatures in presence of two witnesses.
